Solitary Chest Wall Tuberculosis Mimicking a Malignancy Demonstrated on FDG PET/CT

Solitary chest wall tuberculosis is rare. Herein, we reported a case of image findings of chest wall tuberculosis in a 44-year-old woman. On FDG PET/CT, it presented as a solitary soft tissue mass with invasion of adjacent rib, diaphragm, and avid FDG uptake with an SUVmax of 10.19, mimicking a malignancy. The postoperative pathology supported a diagnosis of tuberculosis infection.
